I sent Bill a message last week, (he has not responded yet, but thats OK I don't have the cash rite now) about getting an FU package and 3 chips, I want to chip a '99F350, '99 F450, and '00 F550 all with auto. I am told they are the same definition file.

Are the FU tunes, PCM specific or Definition File specific? Can I run one FU package (with additinal) chips on these 3 trucks (same definition file)?

i was thinking it would be nice to run able to run the HPOP at max psi from 1800rpm and up:evillol:, at like 75% throttle so it wouldn't down shift.

The trucks with 3.73 cruise nice at 1800ish R's down the highway.

wouldn't the mpg go up with 3000-3200 HPOP psi at 1800-2000rpm cruising rpms?

I had a 10k ohm mod on a '95 PS that gave me like 1-2 mpg gain.

will the rough idle (due to the single shots) hurt anything?

As long as all the trucks are in the same PCM family then you are good to go. :D

yeah I need to get a chip, but I just spent a bunch of cash on trailer brakes and tires. Plus every spirng I buy a lot of fertlizer.

I just put together a big construction hay deal, 7000+ bales so that will help.

5000 miles on single shots, in a Superduty. Fuel milage, mpg
 

I have about 5000 miles on the shingle shots. Have haven't unhooked my 32' flatbed goosneck from this truck since I put in the injectors and the HPOP in.

I have a 91 gallon and 40 gallon fuel tank, I fill up at the same place most of the time (Pride in Palmer, Ma 2.999 the past 3 weeks) I check my mileage every fill up. Sometimes I only put on 100 miles then top it off the last tank I ran 1148 miles (took 105 gallons 10.9mpg)

I did a test run last week I filled up 145 miles from home and ran all high way no faster then 60mph mostly 55. I got 15.5 mpg:happy-dancing:, with an empty 7,500# flatbed trailer, with a F550, with 4.88, that is awesome. It was really hard to drive that slow for 3 plus hours. That was the best yet.

the wost was 9.3 mpg hauling a farm tractor (I ran 75 mph 2600 rpm) to New York and then a load of hay home (60-65 mph), this is very good for this kind of hauling.

I plan on putting a ZF6 :woot:and a F450:thumbsdwn: Dana 80 3.73 (unless i can find 3.73 for a spicer110:shrug:) with a locker. Then I should be able to do better mpg.

Welcome to guzzle's Helper/Lift pump Web Page. try this out. It might help your probablem. Make sure you read the whole thing. It talks about high rpm fuel.

thanks epowers777, they have some good stuff, also after reading the bottom of the page, I can see Guzzle and i have much more in common than powerstoke diesel
